项目摘要

The fields of particle physics and cosmology have become inextricably intertwined. Accelerator based experiments, detectors in mines, and telescopes are all needed and used to explore fundamental questions such as the nature of dark matter. The Stanford group led by Principle Investigator Patricia Burchat will complete its investment in the highly productive BaBar experiment at the Stanford Linear Accelerator Center and build a new effort in cosmology through the proposed Large Synoptic Survey Telescope. On the BaBar experiment the goal is to more than double the current data sample by the time the experiment completes its nine-year program at the end of FY2008. The Stanford group will contribute to the maintenance and operation of the SVT and the SVT radiation monitoring system. Members of the group will complete ongoing searches for new physics in rare or forbidden tau and charm decays, and a diverse set of analyses involving charmed baryons. The group is also initiating a new analysis effort involving D mixing and will conduct the final time-dependent Dalitz-plot analysis of B - rho pi on the complete data sample, to extract the CKM angle alpha. The Large Synoptic Survey Telescope is the first ground-based telescope being designed from scratch to address the severe demands on systematic uncertainties needed to fully exploit weak gravitational lensing as a cosmological probe. The LSST will also address cosmological questions through studies of the growth of large scale structure, baryon acoustic oscillations, and Type Ia supernovae. The Stanford group is joining the LSST project collaboration and will contribute to areas that benefit from the experience of particle physicists and aid in the understanding and reduction of potential systematic uncertainties: the development of a detailed simulation, the study of algorithms with existing data sets, and the design and construction of calibration systems. The broader impacts of the program have several foci. The PI will continue her efforts to integrate experimental particle physicists into the LSST project through tutorials and workshops. Members of the Stanford group have been very involved in programs that involve high school teachers and students (including those traditionally under-represented in physics) in basic research. The PI has led efforts to develop new undergraduate majors that increase the cohort of students who receive an education in physics.
粒子物理学和宇宙学领域已经不可分割地交织在一起。以加速器为基础的实验、矿井中的探测器和望远镜都是探索诸如暗物质性质等基本问题所需要和使用的。由首席研究员Patricia Burchat领导的斯坦福小组将在斯坦福直线加速器中心完成对BaBar实验的投资,并通过提议的大型天气巡天望远镜(Large synotic Survey Telescope)在宇宙学方面做出新的努力。BaBar实验的目标是在2008财年结束其九年计划时,将现有数据样本增加一倍以上。斯坦福小组将为SVT和SVT辐射监测系统的维护和运行做出贡献。该小组的成员将完成正在进行的关于罕见或禁止tau和粲衰变的新物理学的研究,以及涉及粲重子的各种分析。该小组还开始了一项涉及D混合的新分析工作,并将在完整的数据样本上对B - rho pi进行最终的随时间的达利茨图分析,以提取CKM角alpha。大型综合巡天望远镜是第一个从零开始设计的地面望远镜,旨在解决系统不确定性的严峻要求,以充分利用弱引力透镜作为宇宙探测器。LSST还将通过研究大尺度结构的增长、重子声学振荡和Ia型超新星来解决宇宙学问题。斯坦福大学小组将加入LSST项目合作,并将在粒子物理学家的经验和帮助理解和减少潜在的系统不确定性方面做出贡献:开发详细的模拟,研究现有数据集的算法,以及校准系统的设计和构建。该计划的更广泛影响有几个重点。PI将继续努力通过教程和研讨会将实验粒子物理学家整合到LSST项目中。斯坦福小组的成员非常积极地参与了一些项目,这些项目涉及高中教师和学生(包括那些传统上在物理学领域代表性不足的学生)的基础研究。PI一直致力于开发新的本科专业,以增加接受物理教育的学生人数。
